In-situ investigation into the hydrogen sorption pathways of High Entropy Alloy based metal hydrides.

DOI

Anthropogenic global warming is largely accepted by society and the need for alternative and renewable fuels is desired. One such alternative fuel is hydrogen, considered to be a renewable and sustainable solution to reducing our reliance on fossil fuels. However, the safe and efficient storage of hydrogen still remains a challenge. High entropy alloy (HEA) based metal hydrides are a class of material that offer a viable way to safely and efficiently store hydrogen. Previous work demonstrated HEAs to have a relatively high capacity and cyclability as a hydrogen storage medium. This proposal seeks to study the storage capacity and cyclability of select candidates by tuning the metal composition to change the properties of the material. With the use of in situ neutron diffraction-TGA the property-structure relationship can be understood to better tune to the ideal metal composition.
